See misjudged his landing approach, and in pulling up from the runway hit Building 101 where the spacecraft was being assembled. Both astronauts were killed, and 14 persons on the ground were injured. As a result, the Gemini 9 backup crew became the prime crew, and all subsequent crew assignments were reshuffled.
